TIME-STAM P.

SPECIFICATION forming part of Letters Patent No. 462,212, dated October27, 1891.

Application filed November 28,1890. Serial No. 372,863. (No model.)

To all whom t may concern:

Be it known that I, JOSEPH D. MALLONEE, of Brooklyn, in the county ofKings and State of New York, have invented a new and use- 5 fulImprovement in Time-Stamps, of which the following is a specication.

My invention relates to an improvement in time-stamps in which aprinting-wheel under the control of time mechanism is caused t lopresent the required type in position to print each successive minute orsubdivision of time lthroughout the day.

The object of my present invention is to simplify the structure andarrangement of J the support for the printing-wheel and the devices forbringing the material to be printed into contact with theprinting-wheel, and to render the structure as a whole more stable andless liable to get out of order.

29 A practical embodiment of my invention is represented in theaccompanying drawings, in which- Figure 1 represents a stamp in sideelevation, the operating-lever being represented as a compound lever.Fig. 2 is an end view of the same.

I have shown in dotted lines the positions of electro-magnets in thebase of the stamp and the connection of their armature by a 3o series oflevers with an operating-pawl in engagement with printing-wheelssuitably supported in the head of an overhanging arm. Theelectro-magnets and the series of levers and printing-wheels are inconstruction and 3 5 arrangement substantially the same as shown anddescribed in Letters Patent No. 434,396, granted to me August 12, 1890,and no claim thereto is made in the present application.

A represents the oase of the stamp, which 4o is here shown asconstructed hollow for the reception therein of electro-magnets, whichare supposed to be in electric connection with a time mechanism notshown. The base might contain a time mechanism connected with the 4 5time-printing wheels without the employment of electricity. The base Ais preferably made substantially rectangular in horizontal section andis adapted to rest upon a table or other suitable support in stableadjustment.

5o From one end of the base A the overhanging arm B extends upwardly andover toward the opposite end of the base, where it is provided with ahead C, in which the aforesaid time printing wheelsand mechanism aresupported. The arm B is formed hollow and forms a housing for the systemof levers or other connection which regulates the movement of thetime-printing Wheels. The said arm B is made broad and wide where itconnects with the base A and gradually diminishes in size as itapproaches the head C, so that the head C may be held firmly inits'position over the base A without any tendency to spring to anyconsiderable degree. In practice the base A, arm I3, and head C may beformed integral. 6 5

A vertically-movable platen D, provided with a cushion d for thereception of the lnaterial to receive' the impression, is so supportedin the base as to move into and out of contact with the type on theprinting-wheels, 7o which are exposed through the under face c of thehead C. In the present instance I have shown the platen D provided witha pair of depending arms E, located upon opposite sides of the base andadapted to slide freely up and -7 5 down between pairs of guide-lugs e,secured to or formed integral with the sides of the base A. Theguide-lugs e, in engagement with the arms E, serve to present the faceof the platen D squarely against the under face of the head C.

The platen D is elevated by means of a lever, as shown in Fig. 1. In theconstruction shown in Fig. 1 a pair of levers F are pivotally secured'to the base A, one upon each 85 side upon suitable pivots f, and havingat one end a loose pivotal connection with the ends of the platen D. Asherein shown, the ends of the levers are provided with perforations fwhich loosely embrace outwardly-ex- 9o tending studs d', fixed to orformed integral with the ends of the platen. It is intended that thereshall be play enough in the connection of the levers F with the platento allow for their slight variation from the line of movement of theplaten due to their swinging in the arc of a circle. The opposite endsof the levers F are provided with curves f2, adapted to receive theroller ends of the branches g of the bifurcated end of the han- Icodle-lever G. The arrangement of the branches g with respect to the endsof the levers F is such that when the handle of the lever G is depressedand the branches g thereby swung rearwardly their engagement with thecurved seats f2 will cause the rear ends of the le vers F to bedepressed, and hence their tor-l ward ends to be elevated, and with themthe platen D. The Weight of the platen D and the ends of the levers towhich it is attached is intended to be sufficient to return the platento its depressed adjustment by gravity. The lever G is convenientlypivoted, as shown at g', to the overhanging armB, and its operating endextends over the head C into convenient position to be pressed by thehand Of the operator.

By locating the mechanism Which turns the printing-Wheelsand theprinting-Wheelsthemselves in a stationary part of the device andbringing the material to be printed into contact With them rather thanthe Wheels themselves into Contact with the material, thedisarrangementof the parts is more etfeotually .ing arm, one member of a compoundlever pivotally secured to the base and connected at one Aend with themovable platen, and another member of the compoundlever pivotallysecured to the overhanging arm, one of its arms having an engagementwith the firstnamed member of the compound lever, and its other armprojecting over the head of the overhanging arm, substantially as setforth.
